The Marbled Salamander is found throughout most of the eastern United States. They are mainly fossorial, spending most of their days underground or under logs. They do come to the surface at night to hunt and during the fall to breed. They travel to breeding sites near depressions in the ground. The male will court the females with nudging, head swinging, lifting, and body-flexing. The male will deposit his sperm on the ground and the female will pick it up with her cloaca. The female then fertilizes the eggs inside of her.
The female lays their eggs under surface material in a depression. She lays between 30 – 200 eggs at a time. The females will stay with the eggs and guard them until the rains come. The rain fills up the depression with water and the eggs will hatch. It then takes the larvae 2 to 9 months to complete their metamorphism.
The female and male have different colors. The male’s stripes are white while the female’s are gray or silver.
